CLEANER FOB ROLLS.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed Inch 80, 1908. :Barial No. 424,095.

erally of a pair of peculiarly constructed.

shoes which are adapted first to be positioned in contact with the rollsto be cleaned and polished, and then to be actuated with areciprocatingmovement longitudinally of such rolls until the latter, which are revolvLing meanwhile, have had their peripheries restored to the desiredcondition, as hereinafter set forth.

Metallic rolls used as conveyors and especially the drier rolls of apaper machine are liable to rust and to become coated with sizin andother substances from the paper which passes over them, so that it isnecessary from time to time to remove such foreign matter in ordertoprevent injury to the paper, and the objectof my invention is toprovide simple and inexpensive but efiicicnt means for doing this work.

A further object is -to produce a cleaner that can be readily attachedto and detached from the frame which supports the rolls to be dressed,and to provide simple means for this purpose, it being understood, ofcourse, that when attached to said frame the device is in operativeposition relative to said rolls.

I attain these objects by the means illustrated in theaccompanyingdrawings, in

Which l igure 1 is aside elevation .of my cleaner showing it applied toa pa r of rolls, portions only of said rolls and the supportingthroughout the several views.

Inferring to the drawings it will be observed that this device comprisestwo shoes 1 having. concave faces adapted. when covered in the mannerdescribed below to be pressed against the peripheries of the rolls, anarm 2 rising from the lower shoe, an arm'3 extending downward from theupper shoe, connecting means. for such arms, and a rocker-arm 4 pivotedat 5 to a lug 6 on said lower shoe. In addition to the aforesaid'membersthere 'are-four spring clips 7 attached at their centers by rivets 8 towhat may be termed the backs of the shoes 1 adjacent to the longitudinaledges thereof and having their ends connected by cross-pieces 4:0,.abolt 9 which passes through a hole 10 in the arm 3 and a longitudinalslot 11 in the'arm 2, a washer 41 and a nut 12 on said bolt, and a.spring 13 having one end fastened to said arm 3 and the other end to alug 14 on top of the arm 4.

The concave faces ot the shoes 1 are covered 1 first with some yieldinmaterial, as leather, and then with pieces 0% sand-paper 15. The leatherpieces, represented at 16, are permanently aflixed to theshoes in anysuitable manner, but the sand-paper 15'is he1d in place by the clips 7the'crosspieces 40 of which are closed on thefolded edges of saidsand-paper, as best shown in Fig. 1, with sufiicient force to preventdisplacement of these pieces during the cleaning operation. When thepieces 15 are worn out, their release is effected by freeing them fromthe clips 7, and then new pieces are placed on said shoes, bent over theends of the latter,

and inserted between said clips or their crosspieces and said shoes, asbefore. The cl'i cross-pieces 40 are provided with handles 1 which. maybe grasped for the purpose. of facilitating the act of drawing saidcrosspieces away from the shoes when it is desired to re lease the endsofthe sand-paper or to engage such ends. A supportingrod '18 and anactuating rod 19 are also associated with the device, and there is anopening in the head 20 of the arm 4 to receive the first-mentioned rod,and a perforated lug 21 on thearm 2 to receive the secondmentioned rod,which lat ter is fastened to said 111 by nuts 22-22 on the rod bothsides of the ug.

In Fi 1 I show fragmentary parts of two drier rolls 23 and of a frame 24which supports them, the frame having a vertical slot 25 therein, and tothis slotted portion of the,

34 adjacent toeach bracket 26 to hold the secured means of a plate 27 onthe outside 3 of the frame and a bolt 28 and nut 29. The

bracket 26 is horizontally slotted at 30 for the bolt 28, which slot andthe frame slot 25 permit said bracket to be properly located for thesupport of one en of the rod 18 which is received in a fork 3 at thefree end of the bracket and there secured against lat- 'eraldisplacement by a removable pin 32.

@n the opposite side of the frame is a similar bracket similarlysupported for the rod 8, except that this second bracket need have onlyan ordinary opening for the end of said rod which is carried by saidbracket. A collar 33 is fastened on the rod 18 by a set-screw arm 4 ismounted on the rod 18 and said rod is secured to its supports with thelower'shoe resting on the lower roll, and then the nut 12 is loosened,the arm 3 is raised to bring the upper shoe against the upper roll,.theslot 11 for-the bolt 9 permitting this to be done, and

operative position.

said bolt is again tightened. If at the start,

however, the shoes are too far apart to enter beneath the rolls, the nut12 must be loosened and the shoes brou ht closer together before anattempt is mini to place the device in After the shoes have been thusbrought into contact with the rolls the tendency of the spring 13 is toforce said shoes hard against-said rolls and to so retain them owing to,the peculiar construction of the parts and the position of said spring.If the rod 19has not already been attached to the lug 21, it is attachednow, and the operation of cleaning and polishing the rolls is proceededwith, while said rolls are in motion, by'grasping said rod and actuatingthe device to and fro the entire length of the rolls until they are freefrom foreign matter and thoroughly scoured, the arm 4 meanwhiie ridingon the rod 18.

With the present supports for the rod 18 said rod is usually left in themachine, therefore, in order to mount the arm 4 on. the rod, it isnecessary to remove the pin 32 and the associated collar 33, swing therod out of the .fork 31', slide the head 20 on to the rod, re

place the latter in said fork, and return said collar to position on therod where it is once more secured by means of its set-screw 34, the rodhearings in the closed bracket and saidhead 20 being sufficiently looseto per restricted to the exactconstruction herein 1 shown and described.I

What I claim as my'invention, and desire to secure by Letters Patent, is

1. The combination, in roll cleaner, of two shoes, means of connectionbetween such shoes, an arm directly connected with one of said shoes andadapted to be mounted to slide on a rod, and a connecting member betweenthe free end of said arm and said means of connection between the shoes.

2-. The combination, in aroll cleaner, of two shoes, arms connectingsuch shoes, an arm connected with one of said shoes and adapted to bemounted to slide ona rod,-and a spring extending between saidlast-mentioned arm and the adjacent shoe arm.

3. The combination, in a roll cleaner, of two shoes, lon itudinallyadjustable arms connecting suci shoes, an arm connected with one of saidshoes and adapted to be mounted to slide on a rod, and a springextending between said last-mentioned arm and the adjacent shoe arm.

4. The combination, in a roll cleaner,.of two shoes provided withconnecting arms, continuous spring clips centrally fastened to suchshoes, cross-pieces connecting the ends of such clips, said clips andcross-pieces being arranged and adapted to grasp the ends of covers onthe faces of the shoes, an arm connected with one of said shoes andadapted 'to be mounted to slide on a rod, and a spring extending betweensaid last-mentioned arm and the adjacent shoe arm.

5. The combination, in a roll cleaner, with a suitably supported rod, ofan arm provided with a head which is capable of being slidingly mountedon said rod, two shoes provided with cornecting arms, one of such shoesbeing provv :led wlth a lug to which said first-mentioned arm ispivoted, and a spring extending between said head and the adjacent shoearm.
